Many times electronic system failures are blamed on the parts when the real cause was human error. Of these human errors, the most common is poor understanding of analog in a digital world. All too often brilliant digital designers have never been taught analog techniques because engineering schools are reducing the amount of analog taught. Maxim, however, is an analog mixed-signal Company. In this application note we share some analog concepts that will help overcome common “human” error and improve analog circuits around the system.
